C30　grade　concrete　was　prepared　to　produce　the　recycled　aggregate　and　the　basic　properties　of　recycled　aggregate　were　investigated　experimentally.　Then　the　recycled　coarse　aggregates　with　different　natural　coarse　aggregates　replacement　ratio　were　used　to　produce　recycled　self-compacting　concrete.　The　cube　compressive　strength　and　elastic　modulus　of　recycled　self-compacting　concrete　with　different　recycled　coarse　aggregate　replacement　ratio　were　tested　respectively,　the　replacement　ratio　of　recycled　aggregate　were　0%,　50%,　70%,　100%.　The　results　indicate　as　follows:　with　the　increase　of　recycled　coarse　aggregate　replacement,　the　workability　of　recycled　self-compacting　concrete　deteriorates;　the　cube　compressive　strength　and　elastic　modulus　of　recycled　self-compacting　concrete　reduce　by　15%　and　20%　respectively.
